Problems solved by technology

[0002] Traditional on-site control technology itself has some insurmountable defects
For example, there can only be one main controller in the network structure, which cannot form a multi-master redundant system, and the system reliability is poor; the data communication method is command-responsive, resulting in poor system flexibility; there is also an insurmountable bottleneck phenomenon in the transmission rate ; Too many and too long on-site connections each transmit different signals, and system interference is difficult to solve; use hand brakes and iron shoe brakes with low operating efficiency and poor safety

Embodiment Construction

[0022] Such as figure 1 As shown, the Lonworks network module is a dedicated communication board, which connects field devices with twisted pairs. The monitoring host computer shown in the figure is a general industrial PC computer; the hump building operation host computer and the monitoring host computer are general industrial PC computers; The type weighing machine is provided by Siemens Company of Germany; the controllable roof with speed measuring pedal means that the controllable roof specially provides speed measurement information; the controllable roof with speed measuring pedal and length measurement means that the controllable roof specially provides length measurement information; The controllers are all the same kind of intelligent field controllers, and the numbers in the illustration are the physical locations of installation.

[0023] The above is a schematic diagram of the SYCS-1 controllable roof control speed regulation system. The controller is the core equ...

Abstract

The present invention relates to a controllable top control system based on the LonWorks field bus technology. Based on the LonWorks field bus technology, the system links a central control room PC machine and a field controller into a network through twisted pair cables; the rolling section and the yard section are respectively provided with a speed measuring device; and the field controller are connected with the speed measuring devices. Compared with the prior art, the present invention has the advantages that the LonWorks field bus technology conveniently links all the equipment to form an interoperable network through the twisted pair cables, which greatly saves the field wiring; the speed measurement, the length measurement and the controllable top group control of each track and the rolling part are completed by the nearby filed controller, which provides high real-time performance; and the performance of the controllable top control system is superior to the completely decelerating top speed control system, and the investment in the equipment is lower than the investment in the reducer and other equipment, so the present invention is in particular suitable for medium- and small-sized hump.

Description

technical field [0001] The invention relates to a distributed control speed regulation system at the hump site of a small and medium-sized railway marshalling yard, in particular to a controllable roof control system based on LonWorks field bus technology. Background technique [0002] Traditional on-site control technology itself has some insurmountable defects. For example, there can only be one main controller in the network structure, which cannot form a multi-master redundant system, and the system reliability is poor; the data communication method is command-responsive, resulting in poor system flexibility; there is also an insurmountable bottleneck phenomenon in the transmission rate ; Too many and too long on-site connections each transmit different signals, and system interference is difficult to solve; use hand brakes and iron shoe brakes with low operating efficiency and poor safety. In response to the above shortcomings, our company has specially developed a ste...
